拖航偏荡角与缆绳临界张力关系分析

Analysis of the Relationship between the Towing Slew Angle and Cable Stress

摘要: 拖航作业中，被拖船经常发生偏荡。为了研究拖航偏荡角与缆绳临界张力的关系，此文以某船为例，在保证被拖船稳性的基础上，确定了被拖船偏荡角度与拖缆张力之间的关系，计算了各个偏荡角度下缆绳张力的极限值，结合拖船上的缆绳张力显示的大小，对拖带作业的安全做出判断。对于监测拖航作业，保障拖航安全具有实际意义。

Abstract: During the towing operations, towed vessels often slew. In order to study the relationship be-tween towing slew angle and cable stress, the paper takes “DA DAN XIA” vessel as the example, under the stability of towed vessel, determines the relationship between towing slew angle and cable stress, and calculates the limit value of cable stress under the different slewing angle. Com-paring with the cable stress on the tow vessel, the towing system can make a judgment for the safety of towing operations. The paper has practical significance for monitoring towing operations and ensuring the safety of towing.
